DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1 of the drawings, there is shown a preferred embodiment of a rotatable interlocking pin system 10. The rotatable interlocking pin system 10 is shown attached to a duvet cover 12 providing a system for securing the duvet cover and a comforter 14 (FIG. 2) together so that the comforter is prevented from bunching up in the duvet cover. One rotatable interlocking pin system 10 may be utilized to secure a duvet cover and comforter together at each corner, and as shown. While the description herein is made with respect to a duvet cover and comforter it is appreciated that the rotatable locking pin system 10 can be utilized to secure multiple layers of adjacent fabrics or web material together. The rotatable interlocking pin system 10 may be constructed to have a variety of shapes in order to decorate the appearance of the duvet cover, while providing the utility of securing the duvet cover and a comforter together.

Referring to FIGS. 2 and 3, the rotatable interlocking pin system 10 includes two separate members 16 and 18 positionable on opposite sides of the duvet cover 12. Each member 16 and 18 include an inward facing side 20 and 22 and an outward facing side 24 and 26 respectively. A coupling pin 28 extends between the members 16 and 18, and detachably secures the members together with the inward facing surfaces 20 and 22 spaced from and facing each other.

The coupling pin 28 is a double ended pin with opposed ends 30 and 32, and a shaft 34 extending between the opposed ends. The opposed ends 30 and 32 are axially receivable by shaft holes 36 and 38 in members 16 and 18 respectively. Each shaft hole 36 and 38 are identical in construction to simplify manufacture. Shaft holes 36 and 38 and the first end 30 of the coupling pin 28 have cooperating structures such that the first end can be captively received by either shaft hole for axially rotation, but cannot be withdrawn from the shaft hole which it was inserted. The second end 32 of the coupling pin 28 is constructed to be frictionally received by either shaft hole 36 and 38, but removable from the shaft hole which it was inserted by overcoming the frictional force. The length of the shaft 34 is divided into two shaft portions 46 and 48. The shaft first portion 46 is diametrically reduced from the second shaft portion 48. The first shaft portion 46 extends substantially from an intermediate location 50 along the shaft 34 to the first end 30, and the second shaft portion 48 extends substantially from the intermediate location to the second end 32.

The shaft holes 36 and 38 can include a first portion 40 of an inner diameter, and a second portion 42 of a inner diameter greater than the inner diameter of the first portion, and a shoulder 44 between the first and second portions. The first end 30 of the coupling pin 28 can be enlarged and insertable through the first portion 40 and into the second portion 42 of either shaft hole 36 and 38, which when fully inserted into the second portion, the shoulder 44 prevents withdrawn from the shaft hole. The diameter of the first shaft portion 46 of the coupling pin 28 is less than the diameter of the first portion 40 of either shaft hole 36 and 38 permitting the free rotation of the coupling pin within the respective shaft hole about a long axis of the coupling pin. The diameter of the second shaft portion 48 is slightly greater than the diameter of the first portion 40 of either shaft hole 36 and 38 such that the second end 32 is insertable into shaft hole by is frictionally retained through engagement of the second shaft portion 48 with the shaft first portion 40.

The first end 30 of the coupling pin can be conically shaped and taper from narrow to wide in a direction from the first end towards the shaft 34, and shoulder 44 being narrower than the wide end of the conically shaped end, thereby preventing withdrawal of the coupling pin 28 from the shaft hole 36, 38.

The second end 32 of the coupling pin 28 may taper to a point, facilitating the second end in piercing through the fabric layers.

Each outward facing side 24 and 26 can be formed to have a decorative or simulative appearance or otherwise treated to have a decorative or simulative appearance. The outward facing sides 24 and 26 can have the same or a dissimilar decorative or simulative appearance providing an interchange and reversible feature to the rotating interlocking pin system 10.

The inward facing sides 20 and 22 of the first and second members 16 and 18 are substantially smooth free from any surfaces that could possible engagement with the fabric layers that would prevent rotation of either or both members on the surfaces of fabric layers about the long axis of the coupling pin 28 in order to prevent tearing, bunching, or otherwise damaging the fabrics.

Referring now to FIGS. 4 and 5, the first and second members 16 and 18, including the first and second outward facing sides 24 and 26, may be constructed to be of a different shape or to have a different ornamental appearance thus providing a reversibility feature to the rotatable interlocking pin system 10 where a user may select which member 16 or 18 to display according to the shape, appearance and/or color of the bodies. In an embodiment, the first and second members 16 and 18, and the first and second outward facing sides 24 and 26, are configured to have a completely different simulative appearance. As an example, the first member 16 and the first outward facing side 24 are shown to be constructed to have a simulative appearance of a flower, and the second member 18 and second outward facing side 26 are shown to be constructed to have a simulative appearance of a bee.

In use, it can now be understood, several layers of fabric, such as a duvet cover 12 and a comforter 14 are secured together by the rotatable interlocking pin system 10 according to the present invention by position the first member 16 on one side of the layers of fabric with the inward facing side 20 thereof facing the fabric, piercing the layers of fabric with the coupling pin 28 by completely passing the second end 32 through the fabric, and attaching the second member 18 to the first member by inserting the coupling pin into the shaft hole 38 of the second member, thereby rotatably connecting the first and second member together and securing the layers of fabric together.
